I added a second temperature probe (the long one). I removed the short probe from its port and then placed the new, longer probe in its port, wanting it to be Temp 1. I put the old probe (the short one) next to it. I now get 0 for both Temp 1 and Temp 2. I rebooted the controller and then removed power and powered-up and still 0 for Temp 1 and Temp 2. I read that there was no code change needed so haven't changed code. Please help.
